Data are presented for erythrocyte protoporphyrin (EP) concentrations determined by the direct reading tecnhique of Lamola et al. (1) Mean concentration of EP in children whose blood lead concentration was less than 30 mug/dl was 34.7 mug/dl whole blood +/- 13.4 (SD). Mean EP concentration in children with blood lead concentrations of 40-59 mug/dl was 80.0 mug/dl. It was 158 mug/dl. It was 158 mug/dl for children with blood lead concentrations greater than 59 mug/dl. All children in this last group had concordant values for Pb and EP on the first or second test.
数据呈现的是通过拉莫拉等人（1）的直接读数技术测定的红细胞原卟啉（EP）浓度。血铅浓度低于30微克/分升的儿童中，EP的平均浓度为全血34.7微克/分升±13.4（标准差）。血铅浓度为40 - 59微克/分升的儿童中，EP的平均浓度为80.0微克/分升。血铅浓度大于59微克/分升的儿童中，该浓度为158微克/分升。最后一组中的所有儿童在第一次或第二次检测时铅（Pb）和EP的值一致。
